Bladebound: The Breathing War Episode 5: “The Demon That Wouldn't Die”

Awesome — now the team is stepping up to face a former Lower Moon Five, meaning this demon used to be one of Muzan’s elite but was demoted or cast out. This episode will test how far Raien, Kiro, Ayame, and Shoji have come — and whether Raien is ready to unlock the true edge of his Shadow Breathing.

🔥 Bladebound: The Breathing War

🗡️ Episode 5: “The Demon That Wouldn't Die”

🪶 Crow Message – Mission Brief

The team is eating near a small shrine when their crows land.

CROW (Raien’s):

“Demon alert. Village of Himorai. A former Lower Moon Five is butchering hunters. Proceed immediately!”

KIRO (grinning):

“Former Lower Moon Five? That means it’s time to go full power!”

SHOJI (gulping):

“Former…? Why is that scarier than current?”

AYAME:

“Because they have nothing left to lose.”

🏞️ Arrival – Village of Himorai

The village is empty. Houses splattered with dried blood. A red moon hangs low. The air is thick with rot.

They find claw marks. Torn clothing. Charred corpses.

RAIEN:

“He’s still feeding.”

😈 Demon Revealed – Hisame the Drowned Flame

Former Lower Moon 5

Burned alive by another demon, now controls steam and boiling blood.

His skin is charred black, eyes glowing red, and his body steams constantly.

Fights with dual clawed chains, and can make the battlefield flooded with boiling vapor.

⚔️ First Clash – Steam Ambush

As they enter a ruined bathhouse, steam floods the room. Screams echo.

HISAME (voice like boiling water):

“New toys... good. I’m so lonely now.”

He attacks from the mist, chains flying.

Kiro is nearly strangled by a chain, but dodges with Lightning Breathing – First Form: Flash Breaker.

Ayame slices through a chain with Water Breathing – Eighth Form: Moon Ripple.

Shoji begins shaking, paralyzed.

RAIEN (to Shoji):

“Get your head right. Or you’ll die in here.”

☠️ Phase 2 – Hisame’s Rage

Hisame releases his Blood Demon Art: “Steam Prison” — the battlefield floods with red mist that melts flesh.

AYAME (screaming):

“It’s like acid!”

Shoji’s clothes begin burning. Kiro gets a chain around his ankle.

RAIEN (stepping forward):

“This fog doesn’t scare me.”

🕶️ Raien Awakens – Shadow Breathing Final Form

Raien finally remembers what Mina told him:

"You can’t kill what's already lost… unless you become like the dark.”

He closes his eyes.

RAIEN (whispers):

“Shadow Breathing… Eleventh Form: Nocturne Requiem.”

Raien’s body disappears entirely into the mist. His Nichirin blade hums, absorbing the shadows.

He reappears behind Hisame, slashing twelve times in one breath — each hit silent.

HISAME:

“Wha—what...?!”

RAIEN (calmly):

“You’re too loud to live.”

💀 Final Blow – Team Finish

Ayame uses Water Breathing – Tenth Form: Frozen Stream, freezing the mist.

Kiro charges lightning through the steam into Hisame’s chest.

Shoji enters Spirit State, empowered by fear and loyalty, and punches Hisame into the wall.

Raien finishes it with a final, delayed slash from Nocturne Requiem — Hisame's head slides off slowly as steam erupts.

🩸 Aftermath

The team stands wounded, exhausted, but alive.

SHOJI:

“Did… did we just beat a former Lower Moon?”

AYAME (smiling faintly):

“We did it… together.”

RAIEN (quietly):

“And I didn’t need saving this time.”

📺 Episode End:

“Even the fog can be split… if your blade is sharp enough.”

Would you like Episode 6 to show the team being celebrated and ranked officially as Intermediate Demon Slayers, or to focus on the return of a major enemy — like a new Upper Moon?
